MACHINE FOR CLOSING JAR S.

SPECIFICATION forming part of Letters Patent N 0. 620,624, dated March'7, 1899.

Application filed November 10, 1898. Serial No. 696,093. (No model.)

To all whom. it may concern:

Be it known that I, ALFRED L. WEIssEN- THANNER, of New York, State ofNew York, have invented a new and useful Improvement in Machines forClosing Jars, which improvement is fully set forth in the followingspecification.

This invention has reference to machines or apparatus for closing jars,bottles, and similar receptacles of the general type illustrated inUnited States Letters Patent No. 590,196, granted to me September 14,1897. In said patent the rowel or part for bending the lower edge of theholding-band under the shoulder on the neck of the vessel wasreciprocated in a radial direction to follow the outline of a vessel ofoval,rectan gular,or irregular outline by connection with a chainpassing around a gage-plate, the rowel being in the form of a circularroller of proper peripheral contour. V

In accordance with my present invention I dispense with the use of thechain and gageplate for the purpose above indicated,employing instead arowel of cam shape corresponding to the oval, rectangular, or otheroutline of the vessel, said rowel being mounted to rotate on a pivotfixed against movement in a radial direction and following the outlineof the vessel by reason of its cam-shape, whereas in my patent abovereferred to the rowel was enabled to follow the outline of the vessel byreason of its radial movement. As in my former apparatus, the rowel ofmy present machine is flexibly mounted, so that it'can yield both inhorizontal and vertical directions to allow for imperfections in theoutline of the receptacle being sealed and avoid breaking the same.

Other differences in the construction of my present machine will be morefully underpart of the machine, and Fig. 5 an elevation of the completemachine.

Referring first to Fig. 5, A is the frame of the machine, and D is thesupporting-plate, upon which the vessel or receptacle to be closed restsand which is movable to clamp said receptacle tightly in place by meansof mechanism similar to that described in my patent already referred to,and which description need not here be repeated.

Referring now to Figs. 1 and 2, A is a depending shaft adapted to besecured in the overhanging arm of frame A by means of a set-screw a. Onthe lower end of the shaft is secured a plate 0 of a configuration conforming to the configuration of the vessel to be closed. Keyed on theshaft above said plate is a gear-wheel B, and loose on the shaft abovesaid gear-wheel, a washer I) being interposed, is an arm E, having asleeve 6 projecting upwardly therefrom around the shaft A. At one endarm E is provided with a depending handle F, by which it may be moved onits axis A, and at its other end it carries a slide 0, normallyoccupying the position shown in Fig. 1 by reason of the action of spring01 around bolt 1), occupying a recess in the end of arm E, said boltbeing screwed into the slide at one end and at its other end passingloosely through an opening in the arm E. Gisashaft passing upwardlythrough slide 0 and through a slot 1) in the arm E and being secured tothe slide, so as to move and be movable with the same. Said shaft has ahandle K. at its lowerextremity and carries a pinion H and a rowel J,rotatably mounted thereon and so connected as to rotate together. PinionH meshes with gear-wheel B, and the latter being fixed, when arm E ismoved around its axis, the pinion H, and consequently the rowel J, isrotated. I

In order to permit the insertion of the vessel to be closed between theplates D and C, it is desirable that the rowel J should be moved to theright from the position shown in Fig. 1 and retained in this positionuntil the vessel has been securelyclamped in place. To that end Iprovide a lever L, pivotally mounted about the sleeve'e on arm E andheld in place by a. bushing e around collar e.

One end f of said lever tapers to a point, which latter bears against aninclined surface h at the end of slide 0. As shown in Fig. 2, the leveris in position to allow the rowel to assume its innermost or operativeposition. By operating the lever to move the slide to the right therowel may be moved outwardly and out of its operative position.

The parts of the machine illustrated in'Figs. 3 to 5 are the same as thecorresponding parts in Figs. 1 and 2, except that the rowel is of suchoutline as to correspond to the rectangular outline of the vessel to beclosed, and a plate M is secured to rowel J, so as to overhang part ofthe edge thereof and engage over the top of the plate 0, beingparticularly useful to prevent the dropping or drawing down of therowel-plate (against the tensionof spring '6) in its action against thelong straight sides of the receptacle.

The operation of the machine is as follows: The vessel having beenclamped into place between the plates D and O and the lever L moved tothe position shown in Fig. 2, the spring d, moving slide 0 and with itshaft G, throws rowel J into contact with the edge of the securingbandon the receptacle to be closed. The operator now grips handles F and Kand rotates arm E, in turnvrotating pinion H and rowel J, the latter byreason of its special contour following closely the outline of thereceptacle and bending the holding-band under the shoulder of the same.

It is of course understood that various forms of rowels are to be usedin accordance with the particular outline of the vessel to be closed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a machine for closing jars or othervessels of oval, rectangular and irregular outline, the combination withmeans for clamping the vessel in position, of a rowel, a carrier for therowel rotatable about the axis of the vessel, and gearing for positivelyrotating the rowel as it revolves about. the vessel, substantially asdescribed.

, 2. In a machine for closing jars or other vessels of oval, rectangularor irregular form, the combination with means for clamping the vessel inposition, of a rowel, a carrier for the rowel rotatable about the axisof the vessel, and gearing for positively rotating the rowel as itrevolves about the vessel, the rowel being of such shape that itsperiphery will closely follow the outline of the vessel without bodilymovement toward or from the axis of the latter, substantially asdescribed.

3. In a machine of the kind described, the combination with means forholding the vessel, a rowel, a carrier on which the rowel is rotatablymounted, the axis of rotation of the rowel remaining substantially fixedduring the operation of closing the vessel, said carrier being mountedto rotate about the axis of the vessel, and the rowel being of suchshape that its periphery will closely follow the outline of said vessel,and means for positively rotating the rowel during its movement aboutthe vessel, substantially as described.

4. In a machine of the kind described, the combination with means forholding the vessel, of a fixed gear-wheel, a rowel-carrier rotatableabout an axis coincident with the axis of the gear-wheel, a pinionrotatable on an axle carried by said carrier and meshing with thegear-wheel, and a rowel connected with said pinion so as to rotate andrevolve therewith, substantially as described.

5. The combination with means for holding the vessel to be closed, of acarrier rotatable about the vessel, a fixed gear-wheel having its axiscoincident with the axis of rotation of the carrier, a slide on one endof the carrier, a pinion meshing with the gear-wheel.

and a rowel connected to and rotatable with said pini0n,,b0th saidpinion and rowel being mounted on an axle carried by the slide, a springagainst which the rowel rests and which permits movement thereof in avertical direction, a second spring pressing the slide toward the axisof rotation of the carrier, and a lever for moving the slide-in theWitnesses:
